Common and Class B shareholders to receive one Class B share for every 5 shares of Common Stock or Class B Stock held

Astronics Corporation (Nasdaq: ATRO), a leading supplier of advanced technologies and products to the global aerospace, defense, and other mission critical industries, today announced a 20% stock distribution of Class B Stock to holders of both Common and Class B Stock. Shareholders will receive one share of Class B Stock for every five shares of Common and Class B Stock held on the record date of June 15, 2026. The Company expects the new shares of Class B Stock to be distributed on or about June 29, 2026. Fractional shares will be paid in cash.

Peter J. Gundermann, President and Chief Executive Officer of Astronics, commented, “We have a long history of ratably distributing Class B shares to all shareholders and our Board of Directors has elected to continue this custom. We believe it rewards our current shareholders and encourages long-term ownership and interest in Astronics.”

Astronics initially distributed shares of Class B Stock to Common and Class B shareholders in 1987, and this would make the fifteenth distribution since that time. After the distribution, approximately 32.1 million Common and 10.9 million Class B shares are expected to be outstanding.

Astronics’ Class B Stock is entitled to ten votes per share while its Common Stock is entitled to one vote per share. The economic value of one share of Class B Stock is equivalent to one share of Common Stock. Class B Stock is not a tradable security, but is convertible at any time and without cost to the shareholder, into one share of Astronics Corporation Common Stock, which is tradable and provides shareholders of Class B Stock access to the market. Subject to certain exceptions specified in our Restated Certificate of Incorporation, as amended, shares of Class B Stock automatically convert into an equal number of shares of Common Stock upon transfer.
